Sorry! The line was blank when I looked at the sheet - didn't realize you had it.

The two lines have had a first round of ECM:
Code:
06/08/21 15:38:50, Finished 5120 curves using AVX-ECM method on C168 input, B1=3M, B2=300M
06/08/21 15:57:19, Finished 5120 curves using AVX-ECM method on C234 input, B1=3M, B2=300M
06/08/21 16:00:25, Finished 640 curves using AVX-ECM method on C196 input, B1=3M, B2=300M
06/08/21 16:00:26, prp36 = 115276336053814400132074298581437151 (curve=848 stg=2 B1=3000000 B2=300000000 sigma=2447590968 thread=26 vecpos=0)
06/08/21 16:16:24, Finished 5120 curves using AVX-ECM method on C198 input, B1=3M, B2=300M
06/08/21 16:32:19, Finished 5120 curves using AVX-ECM method on C203 input, B1=3M, B2=300M
Only factor was a p36 from the C196 of line 128 (3,-9), leaving a C161. The others all survived 5120 curves @ B1=3M (B2=300M)

I'll give the C161 another 5120 @ B1=11M

Hey! what'd'ya know:

Code:
06/08/21 16:37:02, Finished 0 curves using AVX-ECM method on C161 input, B1=11M, B2=1100M
06/08/21 16:37:02, prp40 = 3177752460364283311628886933261181390399 (curve=8 stg=2 B1=11000000 B2=1100000000 sigma=1247095692 thread=1 vecpos=0)
I will finish the C121 with GNFS

The factor is p63, it was a c165 and SNFS 202 job estimated to finish on June 13. I guess it was a pretty lucky ECM strike by somebody who does opportunistic ECM on a bunch of numbers at the same time, without booking.

swishzzz, I am sorry it happened. Good news, I credited it to you anyways, and your Python and observation skills rock! Those factors derived from GCDs still puzzle the authors. :-) Now you also have some free time to pick some new composite(s). SNFS polys are on me.

Could everybody please book (comment in the sheet, post in this thread, or PM me) before processing? I assure you we have enough composites for all of us in the project.

EDIT: swishzzz, an image of my work space these days just to cheer you up!

Number theory homework for a person who processed without booking: https://www.research.ibm.com/haifa/p.../June2021.html
I found only two below googol. It's a friendly challenge to find the highest number you can (and maybe get ** for your solution). Very different skill from ECMing. Or wait, is it?

Do you want to book for SNFS this one then, swishzzz?

 2021-06-08, 23:21 #159 charybdis     Apr 2020 72·11 Posts (8,-8) c274 has the p45 factor 511481640851321883166633948095333636053000239, leaving a c229 - not much use unless there's another ECM hit. t45 is complete on this number, as well as (8,-6) c143, (8,-8) c253 and (6,-8) c148. Planning to run t45 on (6,-8) c179 and (5,-8) c209, as well as t50 on the remaining composites from (7,-8) and (8,-7).

I'll take both composites in (5, 10). The c188 looks like a very similar sized SNFS to what I booked previously and the c146 will be an interesting GNFS target to compare the timings to vs the c188 (assuming both survive ECM).
